Ken Griffey Jr and Mike Piazza were elected to the National Baseball Hall of Fame in balloting announced by the Baseball Writers' Association of America on Wednesday.
Griffey, a 13-time All-Star with 630 career home runs and 10 Gold Glove awards, was named on 437 of the 440 ballots cast in his first year of eligibility, the highest percentage (99.3) in history breaking Tom Seaver's mark of 98.84 percent in 1992.
Griffey also becomes the first player selected number one overall in the MLB Draft to be selected to the Hall of Fame. The Mariners and Reds great is the first centre fielder to be elected since Kirby Puckett in 2001.
Griffey pronounced himself "happy and shocked" at the vote totals in an interview with MLB Network.
After receiving 69 percent of the 75 needed to enter the Hall last year, Piazza made the jump and was elected to Cooperstown in his fourth year on the ballot. Piazza, who received 83 percent of the vote, was a 12-time All-Star, who finished his career with 427 home runs, the most ever for a catcher. The 16-year veteran batted .308/.377/.545 and is the latest draft pick (62nd round) to ever be elected into the Hall of Fame.
The only other players to be named on more than half the ballots were Jeff Bagwell (71.6 percent), Tim Raines (69.8), Trevor Hoffman (67.3) and Curt Schilling (52.3).
Linked to steroids in the past, Roger Clemens (45.2 percent) and Barry Bonds (44.3) gained more votes than last year but remain a long way from the threshold to Cooperstown.
Alan Trammell (40.9 percent) and Mark McGwire (12.3) missed out on election in their final year on the ballot. Among the others who will not be on future ballots because they did not receive 5 percent of the vote were Jim Edmonds (2.5) and Nomar Garciaparra (1.8).
The 2016 Hall of Fame weekend will be held on July 22-25, with the induction ceremony scheduled to take place on Sunday, July 24 in Cooperstown, N.Y.
